I use this shield.

I love the anti-glare ability and the abilty and instructions to clean off micro fibers if you messup. It's a bit tricky to get on, like most shields, but the ability to remove it all you want and try again is a plus. To clean it you just apply scotch tape all over the contact side the peal it off while installing it. The scotch tape removes all the micro hairs and dust.
